410/304/316 Stainless Steel Wafer head self drilling screw
Stainless steel 410, 304 and 316
StainGrip® 410 / 304 / 316 Stainless Steel Wafer Head Phillips Drive Self-Drilling Screws are high-performance structural fasteners designed for ultra-low-profile surface fastening, rapid piercing, and high holding power in light-gauge steel framing, sheet metal panels, HVAC ductwork, and architectural cladding. Available across multiple stainless steel grades—including heat-treated 410 for maximum drilling hardness, as well as SS304 and marine-grade SS316 for ultimate corrosion protection—these screws feature an ultra-wide wafer head that spreads clamping force evenly without distorting soft or thin materials.
Key Features & Technical Benefits
Versatile Stainless Steel Options (410 / 304 / 316 Grades):
410 Stainless Steel: Heat-treated to achieve high surface hardness, enabling the screw to pierce and tap directly into structural carbon steel and metal studs without dulling or snapping the drill tip.
304 & 316 Stainless Steel: Formulated with high nickel and chromium content (plus molybdenum in SS316) to provide maximum long-term resistance against rust, weathering, industrial chemicals, and marine coastal environments.
Ultra-Wide Wafer Head (Maximum Surface Clamping): Features a broad, ultra-flat flange head with a flat bearing surface underneath that spreads clamping pressure evenly across thin metal sheets, preventing head pull-through, panel crushing, and surface distortion.
Precision Self-Drilling Tek Point: Integrated drill bit tip drills, cuts, and taps clean threads into sheet metal, aluminum profiles, and light steel framing in a single fluid operation, eliminating the need for pre-drilled pilot holes.
Phillips Drive System (Universal Tool Compatibility): Deep, precision-cut Phillips cross recess ensures reliable bit engagement and easy installation using standard commercial screwdrivers and power tools.
Full-Length Deep Threads: Precision-formed self-tapping threads provide continuous engagement along the shank, delivering high pull-out strength and long-term joint integrity under vibration.
